HYDBOGARBON BURNER.

Application filed June 12, 1925. Serial No. 36,595.

To all whom z'tmay concern:

Be it known that I, ARTHUR STOCKSTROM, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Hydrocarbon Burners, of which the following is aspecification, reference being had therein to the accompanying drawing.

4 This invention relates to improvements in hydrocarbon burners and itis of that type in which gasoline is fed in relatively small quantities,and is generally referred to in the art as a gasoline drip burner.

The means for feeding the gasoline is well understood by those skilledin the art and therefore it is not illustrated herein.

The object of the present invention is to increase the generatingcapacity of the burner whereby a larger amount of fuel can be vaporizedand burned at the upper end of the combustion section.

A further object of the present invention is to provide twoconcentricseparated troughs havin wide bottoms which in operationequalizes the distribution of fuel and the vapor formed therefrom. Thedouble bowl it is found gives equal distribution of vapor and flamethroughout the entire circumference of the burners under all conditionsof fuel feed regulation. That is, it is found in ractice that the fuelsupply may be cut own so that only a small flame is produced, and theflame will be evenly distributed around the burner.

Another object of the present invention is to provide a burnercomprising concentric troughs, and a combustion section which has itslower end expanded laterally to embrace the upper ends of both of thetroughsithe expanded end bein sufiiciently locate above the upper ends 0the troughs so that there is room for the pro er distribution of thevapor generated .wit 'n the troughs.

Another ob ect of the present invention' is to provide concentrictroughs which are connected at their upper ends by a perforatedhorizontal web, which in operation imtially burn small flames forheating the burner, but when the troughs have become heated then theflame rises above these openings and burns between the combustionsections above. v

A further object of the present invention is to provide acombustionsection with an enlargement at its lower endthat embraces bothof the concentric troughs, the outer 7 wall op osite the enlargedportion of the combust1on section having perforations in I gasoline,that increases vaporization of the gasoline, and also increases thevapor gen.

erated from the gasoline, and enables me to accomplish an evendistribution of vapor .and flame even though the flame be cut down, bothof which, so far as I am aware has not been heretofore accomplished.

Referring now to the drawings:

Figure 1 is a vertical central sectional view of my improved burner.

Figure 2 is a top plan view of the troughs with the combustion sectionremoved.

1 is an outer trough having its top portion open and 2 an innerconcentric trough of the same construction as the trough 1.

These troughs 1 and 2 are connected at their.

upper ends by a transverse web portion 3 which extends throughoutthe-circumference of the'troughs and serves tounite them.

Positioned above the upper ends of the troughs is a combustion sectionwhich consists of two concentric perforated tubes 4 and 5, the saidtubes being locatedvery .much closer together than the combined'width'of the concentric troughs 1 and 2.

Therefore the lower end of the combustionsection 'is constrictedinwardly' thereby enlarging thelower'end of the combustion section asshown at 6 whereby it embraces the upper ends of both of the saidtroughs.

Attention is directed to-the fact that vapor produced from thesetroughs. A pipe 9 has its lower end passing through the lower ends ofboth of the troughs as shown, the inner and outer walls of the outertrough 1 being perforated as shown at substantially equal to the openingin the pipe 9, and the outer wall of the inner trough 2 being erforatedas at 11, whereby the fuel flows om the pipe into the bottoms of both ofthe troughs.

I have found in my work with this burner that when the burner is cold asin starting it is necessary to provide initial flames for heating thetroughs, and these initial flames are provided at the perforations 12through. which perforations air asses, thus causing the flame at thatpoint for initially heating the troughs. "There are a series of theseperforations as clearly indicated in Figure 2 which" shows that theseopenings are arranged short distances apart around the web portion 3.When the burner is heated up, the flame naturallyrises and these initialflames are extinguished, the flame rising above and burning between thetwo tubes 4 and 5.

When the burner troughs are cold and the I initial flames burning, airpasses through the openings 13 of the enlarged portion 6, this airmaintains these flames, as I find it essential that air be admitted inthe enlarged portion for supplying initial flames with the necessaryoxygen for burning.

The usual hood l4 surrounding the combustion section and the troughs isprovided,

I but it formsno part of my present invention, it being substantiallyold in the prior art.

I have not here shown any means for feeding the gasoline to the troughs,as this is well known to those skilled in the art. Ordinarily the usualneedle valve (not shown) is utilized for this purpose.

From the above description it will be observed that gasoline is fed tothe relatively wide bottoms of both of these troughs. It

is then lighted, and it is essential that air be provided formaintaining the initial flames and the main flame from the vapor in thetroughs. Consequently the openings 13 in the enlarged portion providesthe necessary air for maintaining the initial flames which are veryimportant in quickly heating up the troughs so that there will be ageneration of the vapor. The flame as the troughs heat up graduallyrises between the combustion sections, when the initial flames will beextinguished by the upflowing vapor, the'flame being transferred to apoint above in the combustion section. When the combustion section hasbecome heated, the inner perforated wall 5 usually becoming red hot,heat is conveyed by conduction of the hot combustion sections to thetroughs and keeps the troughshot so that the vaporization of thegasoline continues.

I have found in the operation of a device constructed substantially ashereinbefore described that the maximum flame is uniform flame when theflow of gasoline is cut down to a minimum.

Although the burner herein described is especially adapted to usegasoline, yet it will be understood by those skilled in the art, that itis also adapted tovaporize and distribute heavier OllS such for instanceas kerosene. When using kerosene of course it is necessary'that theburner be first heated up by the use of gasoline or if kerosene is usedthat some -means be provided for igniting it in its initial starting.

Changes may be made in the burner without departing from the spirit andscope of the invention so long as they come within a fair interpretationof the appended claims.

Having thus described my invention what I claim and desire to secure byLetters Patent is 1. A hydrocarbon burner comprising concentricallyarranged separated trough, a single combustion section located above thetroughs, the lower end of the combustion section embracing the upperends of the troughs, for the purpose described.

2. A hydrocarbon burner comprising concentrically arranged troughs withopen upper ends said troughs having separated inner vertical walls, asingle combustion section located above the upper ends of the troughs,said combustion section having a lateral enlargement for embracing theupper ends of the troughs, for the purpose described.

3. A hydrocarbon burner comprising concentrically arranged troughs, saidtroughs having flat bottoms for the purpose of increasing vaporization,the troughs having separated vertical inner walls connected at theirupper ends by a horizontal web, a combustion section located above thetroughs, the lower end of the combustion section laterally enlarged toembrace both of the troughs, for the purpose described.

4. A. hydrocarbon burner comprising concentrically arranged troughs, theadjacent walls connected by a horizontal perforated web havingperforations, a combustion section above the said troughs, the lower endof the combustion section laterally enlarged to embrace the upper endsof both troughs, whereby a plurality of initial flames are maintained atthe perforations in the web 5. A hydrocarbon burner comprisingconcentric troughs connected at their upper adjacent walls by atransverse perforated web, a combustion section above the said troughs,the lower end of the combustion section enlarged laterally to embraceboth of the said troughs, the side wall of the outer combustion sectionprovided with openings opposite the enlargement, the parts arranged forthe purpose described.

6. A hydrocarbon burner comprising concentrically arranged troughs withopen upper ends, the upper ends connected by a web and having initialfire openings, a combustion section above the said troughs, the lowerend of the combustion section enlarged laterally a substantial distanceabove the said troughs whereby the said combustion section embraces theupper ends of both of the said troughs.

7. A hydrocarbon burner comprising concentric troughs having their innerand outer walls of substantially the same height, and a combustionsection made up of two perforated tubes, the lower end of one of thetubes enlarged laterally to embrace both of said troughs.

8. A hydrocarbon burner comprising troughs with open upper ends havingtheir inner and outer walls of substantially the same length, theirinner walls connected by a perforated web, and a combustion sectioncomposed of two vertical perforated tubes, one of said tubes enlargedlaterally whereby both troughs are embraced within the lower end of thecombustion section for the purpose described.

9. A hydrocarbon burner comprising two isolated concentric troughsconnected at their upper ends by a transverse web, and a combustionsection composed of two Vertical concentric tubes, the inner concentrictube extending inward above the upper ends of the troughs whereby thetroughs are embraced within the combustion section and a space remainsbetween the lower end of said inner tube and the tops of the troughs.
